That has been provided by Kakoune for a looong time, you get structural
regex interactively as you can subselect matches in current selections,
keep only selections matching/not matching a regex, and push/pop a set
of selections.

That can be nicely implemented interactively by just providing a save/restore
selections mechanism. parallel grouping is then just a sequential list of
commands where you occasionally recall the initial set of selections.
